Q10161501 - One of disk raid appears as free, the controller couldn't rescue the raid set.

Rescue feature only works with the array configuration not serious corrupted.

If rescue does not recovery it, you can recreate the array configuration. Recreate the array configuration means to create new raidset and new volume with fully identical settings as original, but the volume initialization mode must choose “no init” for rescue to skip initialization and keep original data.

Note: You must choose the “no init” initialization mode to avoid data lost. If you create wrong array configuration, you can delete it and recreate a new one. Data in array will not be touched as soon as the initialization mode is “no init”.
